Inventor: MACKENZIE BURTON THORNLEY JR
IPC: B29C48/91
Filed: 1968-10-18
Abstract: 1,248,256. Curing ethylene polymers. GENERAL ELECTRIC CO. 18 Oct., 1968 [1 Nov., 1967], No. 49625/68. Heading C3P. Cured polymeric articles are prepared by a method which comprises fabricating a curable composition comprising an ethylene polymer containing at least 50 mole per cent of ethylene, an organic peroxide curing agent and a mineral filler treated with 0À15 to 4 weight per cent of an organo silane; and passing the fabricated product through a non-aqueous heat transfer medium which is a gas, organic liquid, molten salt or salt solution at a temperature sufficient to effect curing. The ethylene polymer may be polyethylene or an ethylene/propylene or ethylene/vinyl acetate copolymer, optionally in admixture with halogen containing polymers, e.g. chlorinated or chlorosulphonated poly. ethylene or polyvinyl chloride. The curing agent may be dicumyl peroxide, 2,5-dimethyl- 2,5 - di - (t. butyl peroxy) hexane and 2,5-dimethyl - 2,5 - di - (t.butyl peroxy) hexyne-3, optionally with coagents such as polybutadiene. The filler may be aluminium, calcium or magnesium silicate, silica, aluminium oxide or titanium dioxide. Preferred organo-silanes are alkyl alkoxy silanes and vinyl alkoxyl silanes, e.g. ethyl triethoxysilane, n-hexyl trimethoxysilane, dodecyl trimethoxysilane, propyl trimethoxysilane, amyl triethoxysilane, vinyl tri - (2 - methoxyethoxy) silane, vinyl trimethoxysilane, vinyl triethoxy - silane and γ - methacryloxypropyl trimethoxysilane. The compositions may also contain antioxidants, e.g. polymerized trimethyl dihydroquinoline; lubricants, e.g. calcium stearate; flame retardants, e.g. antimony oxide and halogenated compounds; and colorants, e.g. carbon black. Suitable heat transfer media are polyalkylene glycols and esters thereof, glycerol and esters thereof, air, carbon dioxide and nitrogen. The method is particularly suitable for the manufacture of insulated wires and cables.

Title: Improvements relating to power-assisted steering mechanisms of vehicles
IPC: B62D5/06
Filed: 1963-12-19
Abstract: 1,072,234. Power-assisted steering. ANDRE CITROEN SOC. ANON. Dec. 19, 1963 [Jan. 9, 1963], No. 50249/63. Addition to 1,002,557. Heading B7H. In a power-assisted steering mechanism for a vehicle, a shaft 1 transmits steering motion from the steering wheel through a pinion 3 and rack 2 and power assistance is provided by an hydraulic servomotor under the control of a valve 12 actuated in response to axial movement of a rod 10 connected to a cross-pin 6 mounted by rollers in obliquely extending guideways in the pinion 3 and shaft 1. A cam 15 having internal teeth 16 is rotated by a pinion 17 fast with the shaft 1 and is acted upon by a plunger 25 subjected to fluid pressure, the cam surface being such that the resistance exerted by the plunger 25 against rotation of the steering wheel is less at low angles of steer and increases with the steering angle. The plunger is mounted at an angle to the cam and the point of engagement is off centre to the axis of the plunger so that the latter is rotated by the cam. The fluid pressure on the plunger 25 is supplied through a port 28 under the control of a valve 35 which has a fluid inlet 36 and a connection 37 leading to the port 28 from which a port 371 leads to a chamber 38 whereby the pressure fluid produces a force P acting upon the end of the spool of valve 35. At its other end, the spool of valve 35 is acted upon by a force F produced by a centrifugal governor 51 and by an adjustably pre-streesed spring 44 through a member 41 attached to a diaphragm 42. The chamber 43 formed by the diaphragm 42 is connected by a port 40<SP>1</SP> to a drain connection 40 so that the diaphragm exerts a damping action upon the movement of the valve spool. The governor is rotated at a speed proportional to the vehicle speed and the valve spool is moved until a dynamic balance is achieved between the forces F and P so producing a variation in the pressure acting upon the plunger 25 and an additional resistance to steering which varies as a function of the vehicle speed and, by virtue of the spring 44, has a minimum value. The dead-centre position of the plunger 25 relatively to the cam 15 is adjustable.

Abstract: 1385179 Copying paper J SCHMIDT and M UNRUH 23 Oct 1970 [23 Oct 1970] 50530/ 70 Heading D2B A copying paper comprises a support layer coated with a layer of small mutually adherent particles of a vinyl chloride polymer, the polymer having been dyed prior to production of the paper and the polymeric layer being free of waxes, oils, binders, fillers and thickeners. In use, the polymeric particles are transferable on application of writing or typewriting pressure to an appropriately treated surface of a receptor sheet. The copying paper may have a transfer layer on top of the polymeric layer or a receptor layer on the side of the support layer opposite to the side on which the polymeric layer lies. The transfer and receptor layers may comprise an ethylene homopolymer or copolymer. The vinyl chloride polymer may be dyed with one or more cationic, anionic, nonionic, or metal complex dyes, or mixtures thereof. The copying paper may be made by mixing particles of a vinyl chloride polymer in a volatile organic liquid containing a dye until the particles are swollen and dyed, applying the mixture to a support layer, and evaporating the volatile organic liquid. A dye adsorbent e.g. a montmorillonite, or molybdatophosphoric acid, may be added to the mixture to adsorb excess dye. The copying paper may be used in multi-copy sets. Receptor sheets for use with the copying paper may comprise sheets having a receptor layer of the same composition as the receptor layer which may be applied to the copying paper. The support layer may be paper.

Abstract: 1,219,046. Isochromans. INTERNATIONAL FLAVORS & FRAGRANCES Inc. 16 Oct., 1969 [28 Oct., 1968], No. 50979/69. Heading C2C. A process for the preparation of isochromans comprises reacting a Friedel-Crafts reactant, i.e. a compound capable of undergoing a molefor-mole condensation with an alkylene oxide, with a 1,2-lower alkylene oxide C 1-4 , in the presence of aluminium chloride to form an aryl alkanol-aluminium chloride complex, partially deactivating (as defined below) the aluminium chloride in the complex with a free hydroxyl material, e.g. water, a lower alcohol C 1-4 , a lower glycol C 2-7 , and adding formaldehyde to cyclialkylate the aryl alkanol to an isochroman. By the term "partially deactivated" it is meant that the aluminium chloride complexed with the aryl alkanol is so modified that it no longer permits alkylation of the aryl alcohol or unreacted Friedel-Crafts reactant but is sufficiently active to permit and promote cyclialkylation of the aryl alkanol. Suitable Friedel- Crafts reactants are aromatic hydrocarbons optionally substituted by alkyl, alkoxy or halogen radicals and aromatic aldehydes and ketones. In an example 6-oxa-1,1,2,3,3,8- hexamethyl - 2,3,5,6,7,8 - hexahydro - 1H- benz[f]indene is prepared from 1,1,2,3,3-pentamethyl indane, propylene oxide and formaldehyde.

Piston 19 abuts a pressure plate 20 sealed from a pressure chamber 24 in the first piston 16 by a rubber diaphragm 23. Pressure plate 20 carries a valve tappet 22 the bore of which communicates with the atmosphere by a bore 26 in piston 16. Chamber 24 communicates via a valve 27 and constriction 28 with an air reservoir, and through a constriction 29 with an intensifier. When the load cell is balanced, valve disc 33 of valve 27 abuts a seat 32 on piston 16, and the valve tappet 22 abuts the disc 33. If the load applied increases, piston 19 forces the pressure plate 22 upwardly to lift valve disc 33 off seat 32. The pressure in chamber 24 then increases until the load cell is again balanced when disc 33 again abuts seat 32. If the load applied decreases, the pressure in chamber 24 forces plate 20 and piston 19 downwardly, valve tappet 22 losing contact with disc 33. The air pressure in the intensifier and in chamber 24 then decreases until balance is again restored, when tappet 22 again abuts disc 33. The viscoelastic material is said to absorb jolts caused by vehicle travel. A suitable visco-elastic material comprises, by weight, 96.5 parts of a silicone resin, 2.5 parts of a hardener and 1 part of a 1-5Á particle size molybdenum disulphide powder.
